I recently got into the gym and am hoping to add weight and muscle as in fairly skinny. I've made changes to Mr diet to accommodate larger intakes of calories and protein etc, and recently I was adding up totals for major points like sugar.

However, I ran into something concerning and unclear. A quick Google result about how much sugar is too much for one day suggests 36 grams for a male adult. I appear to be in the range of 40 with all the yoghurt, blueberries, protein powder etc.

At thr ssme time, on the nutrition info parts of packaging, I see a gram of sugar being equated to 1%. For example, my granola says it has 27g sugar per serving and it says this is 27% daily value.

So is it 100g sugar a day or 36? Surely it must be the latter but what's going on with the former?
